[0002] Existing LED strips used for wall washers have a wide beam angle, a yellow edge, and a low wall wash height, typically only around 3 meters. Furthermore, their main bodies are typically made of aluminum profiles, which are not bendable. While some use flexible materials, these can only be bent in one direction, not in three dimensions. They also have a large bend radius, are prone to breaking, and have poor pull-out resistance (most use flexible boards or terminal structures).

The silicone sleeve of the utility model is made of flexible silicone material, which is not only waterproof but also easy to bend. The light-emitting units in the silicone sleeve enable the light board to be modularly designed, and the light-emitting units are separately arranged and connected by wires.
